Concept:  The above-given statement is false.

• To keep an eye on all the activities, the environment must have both biotic and abiotic components. Every component is regarded as crucial because it plays a particular and significant role in the ecosystem. 
• Living elements such as insects, pests, and illnesses cause damage to the crops and thus have an impact on their productivity. 
• Weeds impair crop output by competing with the primary crop for resources such as nutrients, light, water, fertilizers, etc., which results in the main crop producing less. Pests feed on the crop by either consuming the plant's leaves or by eating the entire plant, so decreasing its production. 
• The ecosystem's biotic and abiotic elements are connected to one another. Biotic and abiotic substances interact with one another. 
• It is simple to understand how changing one of them will affect the other, thus their combined effect needs to be carefully considered.

The correct statement is biotic and abiotic factors adversely affect crop production.

Hence, option B is the correct option.
